Check Engine Light

P0092 code definition

Fuel Pressure Regulator 1 Control Circuit High

What the P0092 Code Means

The P0092 code means that the fuel pressure has fallen outside the range of acceptable pressures set by the vehicle’s manufacturer. Once the Engine Control Module (ECM) picks up the signal from the fuel pressure regulator that the fuel pressure is incorrect, the Check Engine Light will be illuminated.

What are the causes of the P0092 code?

P0092 could be caused by a faulty part of the fuel system including:

  • Faulty fuel pump
  • Faulty fuel pump relay
  • Faulty wiring
  • Faulty fuel pressure regulator
  • Faulty ECM
  • Faulty injectors
  • Restriction of some kind in the fuel system

What are the symptoms of the P0092 code?

  • Lack of power during acceleration
  • Stalling or hesitation while idling or accelerating
  • Engine dies or is difficult to start
  • Poor fuel economy

How does a mechanic diagnose the P0092 code?

A visual inspection of the system in question is always the best place to start with any diagnosis. If any obvious damages are found, it would be wise to repair them before continuing the diagnostic process. Once all visual damages have been repaired, testing of sensors and the fuel pressure would follow. The integrity of the fuel system sensors and the fuel pressure reading taken will determine how to proceed with this diagnosis.

Common mistakes when diagnosing the P0092 code.

  • Not following all of the proper diagnostic steps to ensure that the correct part is being replaced

  • Not making sure that the fuel level and fuel pressure are noted before replacing any parts (both readings aid in the diagnosis)

How serious is the P0092 code?

Given that this code can affect a vehicle's performance in a major way, it can be considered quite serious. Complications related to this code can cause a vehicle to die, or not have enough power to get anywhere, potentially leaving a driver stranded on the side of the road.

What repairs can fix the P0092 code?

Additional comments regarding the P0092 code.

Be sure that the diagnostic process is carried out in full. Any part of the fuel system that gets skipped over during the diagnostic is a potential cause of misdiagnosis. It is very important to consider every part of the fuel system when trying to find the source of this problem.
